Working on Old Knives

In between the Wusthofs, the Henckels and the Old Chicagos brought to me for sharpening I get a little gem or two...

Old Camp Knife

This was brought to me a few weeks ago, handed down to the owner from his father. It was in good shape really, all it needed was to be sharpened.

I see knives like this, maybe some handmade knives, like one made from a railroad spike the other day, and big old carbon butcher knives. I'm interested in knives and like to see these different knives.

Looking at the picture I see the relief put into the side of the blade of the knife. While some refer to this as a 'blood groove' it is really just a way to remove some of the weight of the knife.
